- Set-top boxes or cable/satellite receivers: These devices may send power-on signals to the TV.
- Game consoles: Some gaming systems can activate the TV when powered on.
- Sound bars or home theater systems: Audio equipment connected via HDMI or optical cables may trigger TV power-on.
- Smart home devices: Voice assistants or home automation systems integrated with the TV can inadvertently activate it.

- Automatic updates causing issues: New firmware versions may introduce bugs or change default settings, affecting TV performance or user preferences.3
- Difficulty finding correct firmware: Multiple firmware versions or confusing file structures can make manual updates challenging.1
